Lars von Trier’s latest film “The House That Jack Built” just premiered at the Cannes Film Festival — and audiences were walking out in droves, according to several critics on the scene. One even said the director had “gone too far this time.”

“Just left Lars Von Trier’s The House that Jack Built. Gross. Pretentious. Vomitive. Torturous. Pathetic,” wrote one critic.

“People are walking out of the new Lars Von Trier movie,” tweeted another. “Like they didn’t know exactly what they were getting into.”

“Walked out on LarsvonTrier [sic]. Vile movie. Should not have been made. Actors culpable,” tweeted another.

Some rushed to the defense of the filmmaker, writing, “I mean, it’s a Lars von Trier movie, what were they expecting?” and “can we talk about the cluelessness of the Cannes audience expecting to be mildly entertained by a lars von trier film about a serial killer lmao.”

Much has been made of von Trier’s return after being declared persona non grata by the festival in 2011. Ahead of his Monday night premiere, IFC Films dropped a teaser trailer for the Matt Dillon film. The ’80s heartthrob appears to be a haphazard serial killer in the throes of an existential crisis. Uma Thurman and Riley Keough make Hitchcockian blonde cameos as von Trier seems to be commenting on his own body of work through Dillon’s character.

In the official Cannes program, a warning appears next to the film’s schedule times: “Certain scenes are likely to offend the sensitivity of the spectators.”

I’ve never seen anything like this at a film festival. More than 100 people have walked out of Lars von Trier’s ‘The House That Jack Built,’ which depicts the mutilation of women and children. “It’s disgusting,” one woman said on her way out. #Cannes2018pic.twitter.com/GsBGCoyHEG

The 2018 Cannes Film Festival will showcase 21 films in competition, another 16 out of competition, 18 in Un Certain Regard, more than two dozen in Cannes Classics and others in the independent Directors’ Fortnight and Critics’ Week sections. Among the riches, here are some that stand out.

“BlacKkKlansman” Spike Lee (Main Competition) The director who some think was robbed of the Palme d’Or for “Do the Right Thing” in 1989 is back in the running with the true story of a black man who infiltrated the KKK in the '70s – but advance footage shows a comic tone, and producer Jason Blum says the goal was “to show what bozos” the Klan is.

“Three Faces”Jafar Panahi(Main Competition)Panahi, who is not allowed to leave Iran and is officially forbidden from making movies, has nonetheless spent the last few years creating a string of wry, smart films about life under totalitarian rule, peaking with “Taxi” in 2015. Any new Panahi film is an event, and his first to land in the main competition in Cannes has already made him the betting favorite for the Palme d’Or.

“The House That Jack Built” Lars von Trier (Out of competition) Matt Dillon as a serial killer over a span of 12 years is intriguing enough. But Lars von Trier returning to the festival that declared him “persona non grata” for his press-conference comments about Hitler in 2011 — that’s a riveting story all its own.

“The Image Book” Jean-Luc Godard (Main Competition) We know the director probably won’t show up, and we know his film will be challenging and elusive. “The Image Book” is reportedly an essay about film that comes exactly 50 years after a politicized Godard helped shut down the 1968 Cannes festival in solidarity with protests throughout France.

“Whitney” Kevin Macdonald (Midnight Screenings) The director of fact-based narrative films (“The Last King of Scotland”) and documentaries (“One Day in September”) turns his sights to the glorious art and tragic life of Whitney Houston for one of a small number of documentaries in the Cannes lineup.

“Yomeddine” A.B. Shawky (Main Competition) The last time a director’s debut feature was chosen for Cannes’ main competition was 2015, when Laszlo Nemes’ “Son of Saul” made the cut and ended up winning Cannes’ Grand Prize and the Oscar for Best Foreign Language Film. Hoping to follow that daunting path: Shawky’s crowd-funded coming-of-age drama about a young man leaving the leper colony where he was left as a child.

“Cold War” Pawel Pawlikowski (Main Competition) Pawlikowski’s last film, “Ida,” won the foreign-language Oscar, and stills from this film have the same gorgeous black-and-white look and disconcerting, nearly square aspect ratio. It’s a romance set in post-World War II Europe.

“Solo: A Star Wars Story” Ron Howard (Out of Competition) No, it has almost nothing to do with the kind of films that are the heart of this festival. But c’mon, who doesn’t want to see this?

“Girls of the Sun” Eva Husson (Main Competition) Golshifteh Farahani, last seen in Cannes with Jim Jarmusch’s “Paterson,” plays the head of a Kurdish female battalion, and past Cannes best-actress winner Emmanuelle Bercot is an embedded journalist in the Cannes debut from “Bang Gang (A Modern Love Story)” director Husson.

“2001: A Space Odyssey” Stanley Kubrick (Cannes Classics) It may be a 50-year-old movie we’ve all seen many times before, but Christopher Nolan’s presentation of this “unrestored” 70mm print will be looking to prove that a classic film can find a new way to resonate half a century later.

“Burning” Lee Chang-dong (Main Competition) Lee Chang-dong’s films “Poetry” and “Secret Sunshine” both won awards at Cannes, which puts the pressure on for this mystery based on a story by Japanese writer Haruki Murakami. It’s the first film in eight years for the Korean auteur.

“Under the Silver Lake” David Robert Mitchell (Main Competition) Mitchell landed in the Critics’ Week section with his last film, the widely praised horror flick “It Follows,” and this time he’s crafted a film noir drama that finds Andrew Garfield searching for a missing neighbor (Riley Keough) through the underbelly of Los Angeles.

“Fugue” Agnieszka Smoczynska (Critics’ Week) Smoczynska’s first film, “The Lure,” transplanted “The Little Mermaid” to a Polish metal nightclub; her next one, “Deranged,” will be a sci-fi opera set to David Bowie music. In between she made “Fugue,” about a woman who has lost her memory, and how could it not be intriguing?

“Climax” Gaspar Noe (Directors’ Fortnight) In a rich year for provocateurs (Godard, von Trier … ), Argentinian director Noe might be the most provocative of all, typically stirring up adulation and outrage in equal measure. And given his penchant for forthright sexuality and hallucinatory imagery, a Noe film titled “Climax” is bound to cause a stir.

“Pope Francis – A Man of His Word” Wim Wenders (Special Screenings) The title sounds too reverential, maybe even boring. But Wenders, who won the Palme d’Or for “Paris, Texas” more than 30 years ago, is a probing and sensitive director who aimed to make a film with the pontiff, not about him.

“Arctic” Joe Penna (Midnight Screenings) You might know the Brazilian director as YouTube’s MysteryGuitarMan, but he’s making his feature debut with an icebound adventure story that star Mads Mikkelsen called the toughest shoot he’s ever been on.

“Rafiki” Wanuri Kahiu (Un Certain Regard) A couple of weeks after Kahiu’s film became the first Kenyan movie to land a Cannes premiere, it was banned in its home country because of the lesbian relationship it depicts. The ban ought to make it even more of a must-see.

“Dead Souls” Wang Bing (Special Screenings) To borrow a phrase from Eugene O’Neill and from a Bi Gan film playing in Un Certain Regard this year, this one is a real long day’s journey into night. Chinese director Wang Bing is known for his epic-length documentaries, and Dead Souls is an 8-hour-and-15-minute exploration of China’s Cultural Revolution, more than double the length of anything else in the official selection.

“The Man Who Killed Don Quixote” Terry Gilliam (Closing night) A strife-ridden 19 years in the making, this may well be the most troubled film production in history -- and more of a must-see than any recent closing-night film, assuming its screening isn’t killed by a lawsuit.
